staging: fbtft: fb_st7789v: reset display before initialization 



In rare cases the display is flipped or mirrored. This was observed more
often in a low temperature environment. A clean reset on init_display()
should help to get registers in a sane state.

Fixes: ef8f3177 (staging: fbtft: use init function instead of init sequence)
